Unlike other line-oriented input functions in strbuf.c, this hardcodes the
LF as the terminator, hence is not capable of reading -z output.  As an
internal function to the bundle reader implementation, that is perfectly
fine, because we know lines in bundle ends with '\n'.

But if we were to promote this to a generic API, that aspect of this
function needs to be reconsidered, and if we decide to allow non-LF line
terminator for consistency with other functions, the current callers in
this function have to pass an extra parameter "term" to it.

We simply do not have enough datapoint to see if it is worth it to promote
this to strbuf.c with such a change, especially when there is no other
caller to it.  That is why we said "Eventually" here when we introduced
this function at e9ee84c (bundle: allowing to read from an unseekable fd,
2011-10-13).

I do not think the situation changed yet in any way since then.
